OF LINKOPING, SWEDEN MIA CHINE FOR MAKING AND APPLYING CAPS TO BOTTLES AND :THE LIKE Application filed February 17, 1928, Serial No. 88,975, and in Sweden November B, 1925.

This invention relates to a capping machine in which several tools are used for themaking of the caps and applying them to bottles or the like, and the invention is main 1y characterized in that these tools are connected to each other by a guide with pneumatic means to remove the capfrom the forming tool and project the formed cap into the guide, then transmitting the same to the next tool and so on.

How the device may be made according to this invention, is shown in the accompanying drawings,.where Fig. 1 is a plan view of a capping machine with a single applying or closing mouth piece, which machine is made according to the invention. Fig. 2 shows a detail of the device in larger scale. Figure 3 is a front view of the machine showing certain parts in section. Figs. 4 and5 show how 9 the device is applied to a machine with several rotary applying mouth pieces, Fig. 4 being a plan view, seen partly in section, of the device and Fig. 5 being an applying mouth piece in vertical section along the line 55 in Fig. 4.

In all figures, 1 indicates the stamping and bending tool (forming tool). 2 indicates the packing in-laying tool, or more strictly speaking its stamp, which is movable up and down in the usual manner. 3 indicates the applying tool, which has a mouth piece 4, wherein each bottle is vertically brought in from below at the same time that a cap is i .5 brought into the mouth piece from the side through an opening 5 in its':wall. The tool 1 is mounted in a slide block 25-of the frame 26, said tool being moved upwards and downwards as usual by an eccentric shaft 27 driven by an electric motor or from another source of power, to which the shaft 27 is connected by a worm gear 28 and a shaft 29. The tool 2 is mounted in another slide block 30 of the frame 26 and moved upwards and down- .45 wards by the eccentric shaft 27. The tool 3 is mounted on the table 32 and is driven as usual by a lever 33, in Figure 3, shown from the end, said lever 33 being swingable about. b

a bolt 34 and connected to the drive shaft by means of the usual mechanism, not shown.

The working of the tools 1, 2 and 3 are passed over here, as such tools are already known.

According to this invention the tools '1, 2 I

and 3 are connected with each other by a guide 6 formed by two parallel strips a of. sheet metal or the like, said strips being so placed and arranged on the table 32 in relation to the tools, that the cap may be brought in the guide 6 from the tool 1 to the tool 2 and from the last mentioned tool to the tool 3 by means of a current of air acting on it, thus pneumatically. A cover member 7 is disposed over the guide 6 as illustrated in Figures 1 and 2, This air current is caused here by means of a blast 8, from the pressure chamber of which a pipe 9 leads, the outlet of which pipe is situated at some distance from the tool 1 and directed against the guide 6, so that the current of air rushes forward in the same. As soon as the tool 1 releases the formed cap, this is received from said tool and projected into the groove 6, by the current of air. By said current of airthe ca is further transmitted ,in the guide 6, until-1t is stopped immediately under the stamp 2 by a blocking member 10, which is automatically moved into the guide every time a cap comes from the tool 1 but thereafter leaves the way clear for'the cap, so that this is caught by the air current and further advanced as soon as the stamp 2 releases the same. The blocking member here receives its movement from the stamp 2 and is by means of a screw 11 arranged on the side of the stamp which is turned from the tool 1. A vertical groove 12 for the screw in the blocking member 10, and a yielding washer 13 arranged between the head of the screw 11 and the blocking member, allow a certain free movement up and down of the member in relation to the stamp, and this free movement in connection with the stops limiting the movement of the member is used for-moving the blocking member in and out of the desired blocking position. The upward movement of the blocking memberis thus limited by a 'sto or shoulder-14 fastened on the machine tab e, and its downward movement is limited y the machine table- B the upward movement of the stamp the locking member is stopped by the shoulder 14, as soon as it comes out of the guide, but the stamp continues its member itself may of course be arranged in Y many different ways. When the packing is laid in the cap and the stamp and blocking member have gone upward, the cap is transported in the guide 6 by the current of air to the tool 3. It enters the mouth piece of the tool through the opening 5, and is'stopped thereby the mouth piece wall on the opposite side in a position directly above the bottle. For holding the cap in this position, until the top of the bottle is moved into thesame, the device is so arranged, that openings 16 in the mouthpiece opposite the opening 5 areconnected with the suction chamber of the blast through a pipe 18, so that the cap at its moment of entry into the mouth piece is sucked to its wall, where it is held, until the bottle during its upward movement catches it. As is evident from the foregoing, the cap is moved directly from the packing inlaying tool to the mouth piece 4.

In order to insure I the transport of the cap from tool to tool the groove 6 is provided with covers. The guide may of course be arranged in'other ways than those described here. Through the arrangement of this guide the caps may be transported by means of currents of air independent of the distance between the different tools. The tools ,consequently need not'necessarily be arranged in one and the same machine. If the cap is not to be provided with a packing, a guide may be arranged for conveying the cap from the stamping tool directly to the closing tool.

In the embodiment described above there is only one mouth piece 4, to which the bottles may be brought in turn by means of an automatically working device. The embodiment shown in Figs. 4 and 5 differs from that shown in Fig. 1 in that respect, that in the same several applying mouth pieces 4 are used. These are arranged in a. continually rotating frame 20, which rotates around the stationary pillar a2. Through this the suction pipe 18 is inserted and its mouth-piece length ened along the circumference of the pillar a distance indicated by y. In the frame 20 at each mouth piece 4 openings 16 are arranged on a level with the mouth piece of the suction pipe 18, so that the suction holds the cap securely during the rotation until the {bottle receives it. By the rotation of the frame each mouth piece when passing between the end of the guide 6 and the mouth piece of the suction pipe 18 receives a cap brought by the air current from the packing inlaymg tool 2 and the cap is held by suction until the top of the bottle is moved into it, and during the passage of the roll a it is fastened on the bottle. This embodiment ofiers the advantage over the former that the bottles, instead of being moved forward stepwise, are continually-being moved during the process whereb a considerably greater capacity is attaine Having now described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A capping device of the character described, comprlsing a tool for stamping and bending a blank, a packing inlaying tool and a tool for applying the cap to a bottle, a guide after releasing the same from said tool, comprises a blocking member slidable on and moving together with a stamp belonging to the inlaying tool, and elements for limiting the movement of the blocking member where.- by the latter stops the cap when the stamp is moving downwards and releases said cap when the stamp is moving upwards.

3. A capping device of the character described, comprising a tool for stamping and bending a blank, a tool for applying the cap to a bottle, a guide running from one tool to another, and pneumatic means to remove the cap from the stamping and bending tool and transmit it through said guide to the applying .tool.

A capping device-of the character descrlbed, comprising a stamp for forming the caps from a blank strip,-a tool'for applying the cap to a bottle, a guide running from the stamp to the applying tool, and pneumatic means to remove the cap from the stamp and transmit it through said guide to the applying tool, said tool being provided and connected with suction means holding the ea in the tool until it is applied to the bottle.

In witness whereof I have hereunto signed my name.
